Will Palmer	0769854f3d	object name: introduce '^{/!-<negative pattern>}' notation To name a commit, you can now use the :/!-<negative pattern> regex style, and consequentially, say $ git rev-parse HEAD^{/!-foo} and it will return the hash of the first commit reachable from HEAD, whose commit message does not contain "foo". This is the opposite of the existing <rev>^{/<pattern>} syntax. The specific use-case this is intended for is to perform an operation, excluding the most-recent commits containing a particular marker. For example, if you tend to make "work in progress" commits, with messages beginning with "WIP", you work, then it could be useful to diff against "the most recent commit which was not a WIP commit". That sort of thing now possible, via commands such as: $ git diff @^{/!-^WIP} The leader '/!-', rather than simply '/!', to denote a negative match, is chosen to leave room for additional modifiers in the future.

Will Palmer	06b6b68ff9	test for '!' handling in rev-parse's named commits In anticipation of extending this behaviour, add tests verifying the handling of exclamation marks when looking up a commit "by name". Specifically, as documented: '<rev>^{/!Message}' should fail, as the '!' prefix is reserved; while '<rev>^{!!Message}' should search for a commit whose message contains the string "!Message".

Elia Pinto	9fe281b342	t/t1511-rev-parse-caret.sh: use the $( ... ) construct for command substitution The Git CodingGuidelines prefer the $(...) construct for command substitution instead of using the backquotes `...`. The backquoted form is the traditional method for command substitution, and is supported by POSIX. However, all but the simplest uses become complicated quickly. In particular, embedded command substitutions and/or the use of double quotes require careful escaping with the backslash character. The patch was generated by: for _f in $(find . -name "*.sh") do perl -i -pe 'BEGIN{undef $/;} s/`(.+?)`/\$(\1)/smg' "${_f}" done and then carefully proof-read.

Richard Hansen	75aa26d34c	peel_onion(): add support for <rev>^{tag} Complete the <rev>^{<type>} family of object descriptors by having <rev>^{tag} dereference <rev> until a tag object is found (or fail if unable). At first glance this may not seem very useful, as commits, trees, and blobs cannot be peeled to a tag, and a tag would just peel to itself. However, this can be used to ensure that <rev> names a tag object: $ git rev-parse --verify v1.8.4^{tag} `04f013dc38` $ git rev-parse --verify master^{tag} error: master^{tag}: expected tag type, but the object dereferences to tree type fatal: Needed a single revision Users can already ensure that <rev> is a tag object by checking the output of 'git cat-file -t <rev>', but: * users may expect <rev>^{tag} to exist given that <rev>^{commit}, <rev>^{tree}, and <rev>^{blob} all exist * this syntax is more convenient/natural in some circumstances Signed-off-by: Richard Hansen <rhansen@bbn.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>	12 years ago

Nguyễn Thái Ngọc Duy	32574b68c5	get_sha1: support $commit^{/regex} syntax This works like ":/regex" syntax that finds a recently created commit starting from all refs, but limits the discovery to those reachable from the named commit.
